BACKGROUND The aim of this study was to assess the effectiveness and complications of rigid endoscopy (RE) and flexible endoscopy (FE) for the extraction of esophageal foreign bodies (FB) in adults. MATERIAL AND METHODS A retrospective analysis was conducted on the medical records of 216 adult patients with esophageal FB impaction treated at Peking University Third Hospital, Beijing, China, b...
the study aimed to come up with a list of specific macroalgae species, which could be used to biomonitor specific metal elements in the coastal waters of east africa. water extraction, edta, aqua regia extraction and optimized bcr 3-step sequential extracts were used to mimic bioavailable metals under various environmental conditions. the results indicated that ulva lactuca could be used as a ...
Abstract TBP extraction in nitric acid system is the core purification process of wet method for uranium refining and conversion. Reextraction based on fractionation was proposed, according to characteristics requirements extraction. The operation line step reextraction were obtained through mathematical model, control law explained. bench test carried out investigate stable concentration varia...
UNLABELLED This retrospective study compared the effects of single and multiple administrations of (186)Re-hydroxyethylidenediphosphonate ((186)Re-HEDP) on palliation and survival of prostate cancer patients presenting with more than 5 skeletal metastases. METHODS A total of 60 patients were divided into 3 groups. Group A (n = 19) consisted of patients who had received a single injection; gro...
RGB-IR cross-modality person re-identification (ReID) can be seen as a multicamera retrieval problem that aims to match pedestrian images captured by visible and infrared cameras. Most of the existing methods focus on reducing modality differences through feature representation learning. However, they ignore huge difference in pixel space between two modalities. Unlike these methods, we utilize...
We have developed an active Q adaptor (AQA) to achieve integration of multiple management protocols and dynamic modification of managed object (MO) definitions. To achieve dynamic modification, we introduce a new MO framework, called dynamic-MO, which has the ability of modifying its own definition. A dynamic-MO is composed of meta-data and some behavior programs. Meta-data lists attributes of ...
the electrocatalytic degradation of methyl orange (mo) on pbo2-tio2 nanocomposite electrodes was studied by cyclic voltammetry and bulk electrolysis. the results reveal that pbo2-tio2 nanocomposite electrodes possess higher oxygen evolution overpotential than pbo2 electrodes and the electrocatalytic degradation of mo on the electrodes is direct oxidation process. the influence of experimental p...
ABSTRACTBackground: An electron beam generated X-ray spectrum consists of characteristic X-ray and continuous bermsstrahlung. The aim of this research is calculating and comparing X-ray spectra for different target filter of mammograms. Materials and Methods: Monte Carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the X-ray spectra. MC...
Abs tra ct. For the simplest of the disc rete mod els of the Boltzmann equations , the Broad well model, exact solutions have been obtained by Co rnille [15.16] in the form of bisolitons. In the present paper, we build exact solutions for more co mplex mod els. 1.
